Hi Guys
I’m glad to read that you like the magazines. The Fall issue was just mailed with the calendar this week. We like to have the online version available for members ahead of time. Thanks!
Yes, kudos all round, Brad. The magazine is the heart of the Association. You do a great job.
By the way, I found an error in the H.B. Dow ledger on the last page of that article. It listed the .22 WRF as having a 1:20 rate of twist.
That didn’t seem right, so I ran a patch through my Model 1890 and checked the distance for one complete rotation. It was 1:14.
Next, I pulled a bullet and ran it through the Greenhill formula. The .22 WRF shoots a 45-grain bullet that’s 0.487″ long. Mine clock out at 1,401 f.p.s. According to George, it needs a 1:15 twist to be stabilized.
Interesting, eh?
Pete
